Abstract: <P>PROBLEM TO BE SOLVED: To prevent the generation of wrinkles in a bent inner peripheral part while ensuring the outer water pressure-resistant strength of a bent outer peripheral part even in such a case that there is a large bent part in piping or there are many cranks in an existing pipe such as the attaching pipe or the like of a sewage pipeline.  <P>SOLUTION: For regenerating the existing pipe 12 by lining the inner surface of the existing pipe 12 with a regeneration pipe 1 made of a synthetic resin, the regeneration pipe 1 of which the outer diameter before regeneration is 70-90% of the inner diameter of the existing pipe 12 is used without lining the existing pipe 12 with the regeneration pipe 1 slightly expanded in its diameter. This regeneration pipe 1 is inserted into the existing pipe 12 and largely expanded under heating and pressure to line the inner surface of the existing pipe 12. Further, when the existing pipe wherein pipes having different calibers are present in the same piping is regenerated, the regeneration pipe, of which the nominal diameter before regeneration is smaller than that of the minimum caliber pipe in the piping by one size, is used. Further, a material of the regeneration pipe 1 comprises a hard vinyl chloride compounding agent with a glass transition temperature of 30-80°C.  <P>COPYRIGHT: (C)2003,JPO
